Q2016LH6

Triacs Overview

The Q2016LH6 is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features a maximum repetitive peak off-state voltage of 200V and an RMS on-state current rating of 16A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220AB package with two leads. Key electrical characteristics include a gate trigger voltage of 1.3V and a holding current of 50mA. This component belongs to the Qxx16xHx series, offering high dv/dt capability and robust performance in industrial switching environments.

Triacs Feature Summary

• Bidirectional conduction for AC load control
• High thermal stability with extended operating temperature range
• Robust gate triggering sensitivity for reliable switching

Triacs Applications

• AC motor speed control circuits
• Solid-state relay (SSR) output stages
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix 'H6' against the official Littelfuse datasheet to confirm pinout configuration and packaging type. Ensure the selected variant matches the required voltage and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if environmental regulations apply to the end product.

Triacs Selection Notes

Select this triac based on the 200V voltage rating and 16A current capacity requirements. Consider the TO-220AB package for adequate heat dissipation without additional heatsinking in moderate duty cycles. Evaluate the gate trigger characteristics to ensure compatibility with the driving circuit's output voltage levels. Compare against higher voltage variants if system transients exceed 200V.

Triacs Part Context

This component is part of Littelfuse's Qxx16xHx series of high-performance triacs. The series is engineered for general-purpose AC power switching, balancing high current handling with sensitive gate drive requirements. These devices are commonly used in consumer appliances and industrial controls where reliable AC regulation is essential.

Triacs Replacement Considerations

Direct replacements may include other 200V 16A triacs in TO-220 packages from manufacturers such as STMicroelectronics or Vishay. Verify that substitute parts match the gate trigger voltage and holding current specifications. Ensure the replacement device offers equivalent thermal resistance and mechanical dimensions for board compatibility.
